SN74LVC2952APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2952APW is an octal bus transceiver and register with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation on all ports. The device consists of two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Data is stored on the low-to-high transition of the clock input when the clock-enable input is low. Taking the output-enable input low accesses the data on either port. The maximum propagation delay is 8.2 ns at 3.3 V.

• Supports mixed-mode signal operation allowing use as translators in mixed 3.3-V/5-V system environments
• Includes Ioff circuitry to support partial-power-down mode and prevent damaging current backflow
• Features latch-up performance exceeding 250 mA per JESD 17 specification

Buffers, Drivers, Receivers, Transceivers Applications

• Octal bus transceivers requiring bidirectional data flow
• Mixed-mode signal translation between 3.3-V and 5-V logic systems
• Partial-power-down applications utilizing Ioff functionality

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP package with a tube quantity of 60 units. Confirm the operating temperature range is -40°C to +85°C. Ensure the component status is checked against the latest manufacturer production data to confirm availability for new designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring dual 8-bit registers within a single octal bus transceiver. It is suitable for designs needing 3-state outputs and mixed-voltage interface capabilities between 3.3-V and 5-V domains. Consider the TSSOP-24 package constraints and thermal impedance characteristics during PCB layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2952A family of octal bus transceivers and registers. It is designed for 1.65-V to 3.6-V VCC operation and provides bidirectional data storage between two buses. The device ensures high-impedance states during power-up or power-down when OE is tied to VCC through a pullup resistor.
